Is input by the controller 7. The controller 7 controls the control valve 3 by comparing the input value (5 to 15%) with the value measured by the densitometer 6. A part of the ice slurry S in the mixing tank 1 pumped up by the pump 8 is cooled by the refrigerant of the refrigerator 9 while passing through the ice making device 5 to become the grain ice i and returned to the mixing tank 1. Most of the ice slurry S is returned to the heat storage tank by the pump 10.
